And heros welcome. The superstar surfer returns home overnight after that shark scare. Now a worldwide phenomenon. He opens up about that Close Encounter to friends and family joking about why he was targeted. I had fish the night before. Maybe thats why. As the internet goes into overdrive with its new hero. Im glad he can joke about a shark attack right now. But were all going to have to get into the water to escape this heat. Im telling you. Well begin with the sizzling heat. Millions of americans in ten states from texas to virginia under heat warnings and advisories. It was the hottest day of the year in major cities across the northeast. And temperatures could top 90 degrees again. Ginger, where else would she be but outside in the heat for us this morning. Good morning, ginger. Oh, good morning to you, robin. This is supposed to be the hottest time of year, and, boy, is it turning out to be. Already in the low 80s this morning. Thats one of the issues. The temperatures are not dropping. The other issue, a lot of moisture in the air. Thats what makes it dangerous. Look at some of the heat indices this morning. It feels already like 90 in washington, d. C. Thats closer to their average high for this time of the year. You have the heat and humidity and thats when you start to get into the danger zone. This is worse than brutal. Its treacherous. Reporter oppressive, blistering heat. Its awful and its very, very, very hot. Reporter overnight, parts of new york city without power. In staten island, portable light towers brought in illuminating officers directing traffic. No power forcing this hospital to run on backup generators. Brutal. Reporter power lines igniting from the overload. New york city, now in the midst of what will likely be the First Official heat wave weve had since 2013. Nearly a dozen firefighters treated for heatrelated ailments. Some rushed to the hospital. Check on your neighbors. Particularly our senior citizens. Reporter in philadelphia, city buses free for seniors to ride, keeping them out of that heat and cooled off. In louisiana, and in texas, roads buckling. Heat indices above 105. Flames rolling out. Reporter in New Hampshire take a look at this. Nascar driver alex bowmans right front tire literally burning rubber as temperatures soared to 126 degrees on the track. The other problem is the heat is cumulative. Thats why we have advisories in effect from texas all the way to southern virginia, southeast virginia really. Excessive heat warning for florence, South Carolina up to wilmington, north carolina. The numbers are going to soar above 106. Jackson, mississippi, what it will feel like. Good news, everybody. If you are north of philadelphia, youre going to see some fresher, much less humid and cooler air going into the end of this week. So things are going to improve, george. Okay, ginger, thanks very much. To the race for president now. Your voice, your vote and our brandnew abc News Washington post poll. Big news for donald trump jumping out to the widest lead yet on the republican side. Nearly double the support of his closest rival. Lets get more on this from jon karl. And jon, a pretty stunning surge there. But it does come with an asterisk. Reporter stunning surge with a big caveat. First the surge, look at the numbers, trump weighs in with 24 support among republicans. That is twice as much as jeb bush. And it is the biggest lead we have seen by any republican so far in this race, by far. But heres the caveat. Most of this poll was conducted before his controversial comments on john mccain. Among those surveyed after those comments, his support went down conspicuously. And take a look at this mornings daily news, the New York Daily News. Trump is once again getting hammer over those comments. The daily news pointing out trump received five deferments avoiding the draft in vietnam while mccain was spending his time as a p. O. W. Yeah lots of questions about his draft record right there. Now, most Top Republican strategists think he wont get the nomination. But theyre worried hes a spoiler. Reporter look at the polls. Jeb bush versus Hillary Clinton, you have a very close race. But if trump jumps in as an independent, suddenly Hillary Clinton wins in a landslide, almost all of trumps support coming from republicans. And, jon, ill be heading to ohio today to interview the Ohio Governor, john kasich. Hell become the 16th candidate right now. Not really registering in the polls, but his profile gives him a lot of potential. Reporter so hard to break through but, look, he is the governor of ohio, he has won election twice in ohio and as you know there probably is no battleground state more significant than ohio. So if anybody has a chance to break through at this late game it may be john kasich. That will be on world news tonight. And Good Morning America tomorrow. Ill now youll scoot out early for that. The latest on sandra bland, the woman found dead in a texas jail cell three days after being arrested during a traffic stop. Police have released new video from outside her cell around the time she died. As her family awaits the results of that private autopsy. Abcs ryan smith has been tracking the case for us. Good morning, ryan. Reporter good morning. Authorities say they believe Sandra Blands death was a tragic accident and not one of criminal intent. But theyre also adding theyre viewing it like a Murder Investigation and now releasing video from inside the jail where she was held during the last moments of her life. This morning, Authorities Say this newly released jailhouse video shows the Moments Police officers realized sandra bland was dead. Hanging in her cell, a garbage bag around her neck. The threehour surveillance tape shows little activity in the hallway leading to blands cell. But watch as this officer goes to check on her, looks through a window and runs back to the main jail area to summon help. This is being treated like a Murder Investigation. Reporter the Texas Rangers now investigating how she died after being arrested in this routine traffic stop. You just slammed my head into the ground. Do you not even care about that . Reporter police placed her in this area of jail cells. You cant see her, but they claim her health was intact. There were no reported injuries by miss bland. No additional medical treatment was requested. Reporter less than three hours before her death, Authorities Say jailers conducted their rounds. A jailer personally spoke with miss bland. Miss bland reported to this jailer, im fine. Reporter later she asked about making agent phone call, one never made. It would be their last conversation with her. An hour later, a guard comes to sandras cell. The jailer looked through the window and observed miss bland hanging from the privacy partition in her cell. Reporter but this video still leaving her family with more questions than answers. It wasnt much of anything there so, of course, thats still was lingering questions. I will tell you that what i think it shows is that its clear that something is wrong. Reporter while a coroner listed sandras cause of death as suicide, Authorities Say theyre not so sure. It is too early to make any kind of determination that this was a suicide or a murder. Reporter police say they expect to release dash cam video of the arrest today. And theyre downloading data from sandras phone indicating she was recording the incident. And as for her family, theyre hoping private autopsy results expected today will help solve the mystery of her death. Thanks very much. Lets talk to dan abrams about this right now. The Police Treating this like a Murder Investigation. But no evidence that anyone went in the cell. Thats right so you have the sheriff and the coroner deeming this to be a suicide. But in essence, what the District Attorney is saying, yeah, i know thats their position. But im still going to do an independent investigation here to determine could there be Something Else . Meaning, you could still look, for example, at the plastic bag. Where there fingerprints . Were there dna . These are important questions that need to be answered. And by the d. A. Coming out and saying, ill look at it as if it were a Murder Investigation, hes saying this isnt over. And im pretty sure hes going to end up handing this to a grand jury to ultimately make that decision. Thats why the autopsy is so important, but also the release of this dash cam video. Right, so the dash cam video is from when shes arrested. Were expecting that to be released today. A somewhat separate issue as to why was she arrested. Did the police behave properly when she was arrested . That will be more important in any civil lawsuit that she may file against the Police Department than necessarily in the Murder Investigation. Why she spent three days in jail as well. Thats right. All right, dan abrams. Thank you very much. Now to new developments overnight in the investigation into that deadly shooting in chattanooga.
